will this hat cover my kid's ear?

My son tried this hat on in the store the other day and it was quite small and did not cover his ears...he's 10 average height/weight so it may fit a younger, smaller boy/girl but I would definitely not buy it for my son as it was that much too small

We have a pile of these hats at home, all size M, for my two boys, ages 6 and 11.5. This hat covers the ears the same as most any other non-earflap hat does - the bottoms of earlobes can be seen, but I think that is normal. These hats look super cool and wash up great, whenever I can get them off their heads.
